Triggers aren't going to negate the sound of acoustic drums, they only make them louder when played through a PA. You should either use sound treatment/ sound proofing in your drum room, get neoprene drum silencers like SoundOffs, swictch to mesh heads which you can trigger or get a pad kit which you can trigger. Yeah you can slap triggers on to your kit and play through headphones, but your neighbors are still going to hear you banging on your kit.
